ROXSTAindustrial – Efficient CO₂ Refrigeration for the new DACHSER Logistics Center
At the DACHSER logistics center in Landsberg, three ROXSTAindustrial units provide energy‑efficient and climate‑friendly cooling. TEKO’s CO₂ technology ensures reliable temperatures and stable quality for sensitive food products.
To ensure the daily cooling of around 100 tons of food, absolute operational reliability is essential. In DACHSER’s new logistics center in Landsberg, the focus was therefore clearly on a future-proof, energy-efficient and climate-friendly refrigeration solution. Together with our partner Kreutzträger Kältetechnik, TEKO supplied ROXSTA Industrial CO₂ rack systems that ensure reliable and sustainable temperature control of the new storage areas.
The result: Stable product quality for dairy and choco-late thanks to maximum operational reliability, high energy efficiency and low operating costs.
The installed systems impress with state-of-the-art technology:
- ECO compressors enable energy-optimized part-load operation.
- EVALIFT technology increases evaporation performance by up to +6 K.
- Adiabatic gas cooling optimizes performance on hot summer days.
- In addition, the TECO₂nditioner ensures constant suction gas temperatures, increas-ing overall system reliability.
Sustainable heat and defrost concepts
Defrosting of the evaporators is efficiently controlled via a brine circuit with buffer storage. At the same time, waste heat from the systems is used to heat office and staff areas. Propylene glycol is used as the medium — safe, climate-friendly and high-performance.
Digital control & transparency
Control is based on customer-specific Wurm systems tailored to the process requirements of Kreutzträger and DACHSER. A web-based visualization with real-time data analysis, trend monitoring and clearly structured dashboards ensures maximum transparency.
Conclusion
The project in Landsberg demonstrates how modern CO₂ technology can be implemented reliably on a large scale. Through close cooperation between DACHSER, Kreutzträger, Wurm and TEKO, a system was created that is tailored to the specific requirements of a high-turnover logistics site.
The installed ROXSTA Industrial systems ensure stable temperatures across all storage areas, enable efficient heat recovery, and guarantee energy-optimized operation throughout the year.
